Answer:
90 degree
Step-by-step explanation:
∠ 1 , ∠2 and ∠3 are three interior angles of a triangle so the sum of these three angles are 180°
From the figure, ∠1 is a right angle means m∠1=90°
m∠1+m∠2+m∠3=180°
m∠2+m∠3=180°-m∠1
m∠2+m∠3=180°-90°
m∠2+m∠3=90°
Answer:
50°
Step-by-step explanation:
the angles should add up to 180. there is a 90° angle abd a 40° angle which adds up to 130. 180-130 gives you rour missing angle if 50°.
Answer: none of those, 276...?
Step-by-step explanation:
You need to know the least common denominator (LCD) of 12 and 23 if you want to add or subtract two fractions with 12 and 23 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 12 and 23 is 276.
Here is a math problem example where you need to know the LCD of 12 and 23 to solve:
3/12 + 2/23 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
276/12 = 23
276/23 = 12
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 23 = 69
2 x 12 = 24
Step 3) Put it all together to solve the problem:
69/276 + 24/276 = 93/276
= 3/12 + 2/23 = 93/276
It's that easy! Once again, the lowest common denominator (LCD) of 12 and 23 is as follows:
276
Answer:
Step-by-step explanation:
From the question we are told that:
Speed of ball 
Length of field 
Generally the equation for Time taken 
is mathematically given by
Therefore it will take the ball to get from one end of the field to the other
Answer:
n(U) = n(AUB) + n(AUB)'
Step-by-step explanation:
The cardinality of the universal set will be to add the cardinalities of both the union of A and B i.e (A U B) and and the compliments of A and B i.e n(AUB)'
